UNITED STATES WILLIAM M. BARNES, or HOLLAND, ivrrssotinr.

COTTON Application filed November To all whom it may concern:

Be it known that I, WILLIAM M. BARNns, a citizen of the United States, residing at Holland, in the county of Pemiscot and State of Missouri, have invented new and useful Improvements in Cotton Choppers, of which the following is a specification.

he object of this invention is to provide a walking or riding straddle row type of cultivator-s with removable attachments for converting the same into cotton choppers.

A further object is to produce an attachment for straddle row type of cultivators for converting the same into cotton choppers, comprising rolling disks which are secured for vertical and longitudinal adjustments on the gang beams of the cultivator, and which are provided with scraping or cleaning means held thereagainst in a particular and novel manner.

To the attainment of the foregoing and other objects which will appear as the nature of the invention is better understood, reference is to be had to the drawings which accompany and which form part of this ap plication.

In the drawings Figure 1 is a side elevation of a combined riding and walking straddle row type of cultivator illustrating the improvement thereon.

Figure 2 is a plan view looking toward the arrows on the dotted line 22 of Figure 1.

Figure 3 is an edge view of one of the rolling disks and the support therefor with. parts broken away and in section.

Figure 4 is a face view of the device disclosed in Figure 3.

Figure 5 is a sectional view on the line 5-5 of Figure 4:.

Figure 6 is a view substantially similar to Figure 3 but showing the supporting means for the disk on the left hand side of the eultivator with parts in section.

In the showing of the drawings the numeral l designates a combined walking and riding straddle row type of cultivator-s. The construction is of the usual class, and therefore a detailed description thereof will not be entered into. The cultivator is, of course, mounted on wheels and carries rearwardly extending beams 2 for the gangs of plows.

In carrying out my invention, the plows are removed from the beams 2, and at determined points on the said beams I adjustably and removably secure brackets for the CHOPPER.

shanks that provide supports for the rolling disks. The brackets include each an outer member 3 and an inner member 4. The outer member is centrally provided with a socket through which the shank 5 passes. The innerand outer members straddle the beam 2 and are secured thereon and together, by adjustable means 6.

The shanks, on the opposite beams are of the same construction, each having its lower portion rounded outwardly, as at 7 Secured on the straight face of each shank, at the juncture of the rounded portion 'Zthereof, there is a bracket 8. Each bracket includes an inner straight portion 9 that is riveted or otherwise secured to the shank. This straight portion terminates in an angle shoulder 10 which merges into a downwardly directed rounded arm 11. Between the rounded portions 7 of the shank and the arm 11 of the bracket there is passed a bolt member 12 engaged by a nut 13. The head of the bolt and the nut contact the shank and the arm 11 of the bracket and force the same into notches in the hollow caps li. Each cap has its inner wall formed with a conical extension 15 that is received in the conical bore of the hub sections 16 secured on the opposite sides of the rolling disks 18. One of the hub sections has a threaded bore and the other hub section has a threaded boss that is screwed through the rolling disk 18 and in the bore of the first mentioned hub section.

On the shoulders 10 of the brackets ll rest rearwardly extending plates 19. The plates have their inner ends straight and are secured by a single bolt or rivet 20 to the angle portion 9 of the bracket 8 and to the shank 6. The plates, from their connected portions, are disposed at an outward angle, as indicated by the numeral 21, and these angle portions have secured thereto by means 22 scraper blades 23. The ends of the plates are formed with angle flanges 21 to contact with one edge of the portions 9 of the brackets 8 and with the shank The blades scrape the rolling disks in the usual manner. The support comprising the plate 19 for the scraper blades, having its lower edge contacting with the flat shoulder 10 of the bracket 8, is effectively held from movement in any direction so that the scraper blades are always maintained in active position with respect to the rolling disks l8. 7

The shanks 5 are provided with any desired number of spaced apertures 24: that pass through the sockets of the brackets, and passing through the outer face of the socket portion of the bracket and entering one of these apertures there is a bolt member 25. In this manner the rolling disks are vertically supported on the cultivator frame, and as previously inferred, the brackets are secured for longitudinal adjustment on the beams for the said frame.

It is thought that the foregoing description, when taken in connection with the drawings, will fully set forth the construction and advantages of my improvement to those skilled in the art to which such inventions relate and that further detailed description will not be required.

Having described the invention, I claim 1- In combination with a straddle row type of cultivators, of a means for converting the same into a cotton chopper, comprising removable and adjustable socket carrying brackets on the beams of the cultivator, rolling disks, supporting shanks therefor having lower rounded portions providing bearings for the rolling disk shafts, a bracket secured on each shank having a shouldered portion terminating in a downwardly rounded arm providing a bearing for the second end of the disk shaft, a plate resting on the angle portion of each bracket, each of said plates having an offset end to engage with the shank and with the connected portion of the bracket, a single element securing the plate to the said portion of the bracket and to the shank, said plate having an angled outer end, a scraper blade for the rolling disk rigidly secured thereon, and means for vertically sustaining the shanks in the sockets of the brackets on the cultivator beams.

In testimony whereof I afiix my signature.

W. M. BARNES.
